[0026] Embodiment 1

[0027] As Figures 1-4 shown, the present invention provides a barreled water filling device with a disposable inner liner, which includes a water filling pipe 8, a support frame 1 and a conveyor belt 2 for conveying water buckets 3. The bottom end of the support frame 1 is suspended with a lifting and guiding ring 11 by four suspension rods 16. A clamping plate 10 is slidably mounted on the suspension rods 16 in the vertical direction. A through hole is provided at the central position of the clamping plate 10. A plurality of clamping members 17 for clamping the edge of the opening of the inner liner are equidistantly arranged on the clamping plate 10. In this embodiment, the clamping member 17 is selected as a clamping plate. In order to improve the clamping force, silica gel cushions can be provided at the top ends of the clamping plate and the clamping plate 10. During use, the opening of the inner liner is unfolded, and the edge of the opening of the inner liner is clamped by a plurality of clamping plates in sequence. A second spring 18 is installed between the clamping plate 10 and the lifting and guiding ring 11 on each suspension rod 16, so that a certain distance is spaced between the clamping plate 10 and the lifting and guiding ring 11 in the natural state. Since the disposable inner liner is made of a flexible material, after the clamping member 17 clamps the edge of the opening of the inner liner, the non-opening end of the inner liner passes through the through opening and is temporarily lifted by the lifting and guiding ring 11. When the water filling pipe 8 extends into the opening of the inner liner and drives the inner liner to descend, the lifting and guiding ring 11 can form a converging effect on the inner liner towards the middle, and the water filling pipe 8 can drive the inner liner to extend to the bottom end inside the water bucket 3. During the filling process, the second spring 18 always provides a stretching force to the edge of the opening of the inner liner.

[0028] A water filling pipe 8 is slidably mounted on the support frame 1 in the vertical direction corresponding to the through hole position of the clamping plate 10. The water filling pipe 8 is a rigid metal pipe. The top end of the water filling pipe 8 is communicated with a water supply device. A guiding boss is provided at the bottom end of the support frame 1 to prevent the water filling pipe 8 from shaking during descent and play a role of stable guiding. The inner diameter of the guiding boss is the same as the outer diameter of the water filling pipe 8. A plurality of water spraying ports 801 are provided at the bottom end position on the side of the water filling pipe 8.

[0029] A driving assembly for driving the water filling pipe 8 to slide up and down is fixedly installed on the upper part of the support frame 1. Among them: The driving assembly includes a wire winding wheel 13 and a motor 14 for driving the wire winding wheel 13 to rotate. A connecting seat 19 is fixedly installed at the top end of the water filling pipe 8. A pulling rope 12 is connected between the connecting seat 19 and the wire winding wheel 13. A return spring 9 is installed between the connecting seat 19 on the outer side of the water filling pipe 8 and the top end of the support frame 1. After the filling is completed, the motor 14 drives the wire winding wheel 13 to rotate in the reverse direction, and the water filling pipe 8 is lifted upward and reset under the action of the return spring 9, so that the lowest end of the water filling pipe 8 is separated from the bucket mouth of the water bucket 3. In order to improve the direction of the acting force on the position of the connecting seat 19 on the water filling pipe 8 and enable the water filling pipe 8 to smoothly move downward against the acting force of the return spring 9, a wire guiding wheel 15 is rotatably installed at the intersection of the support frame 1 and the water filling pipe 8, so that the pulling rope 12 between the wire guiding wheel 15 and the connecting seat 19 is closer to the vertical state.

[0030] In order to enable the water bucket 3 to accurately reach the filling station, that is, the bucket mouth of the water bucket 3 is located directly below the water filling pipe 8, centering and positioning components are symmetrically arranged on both sides of the conveyor belt 2 corresponding to the filling position. The centering and positioning components include a cylinder 5 and an arc-shaped positioning plate 6. The arc-shaped positioning plate 6 is fixedly installed at the output end of the cylinder 5. The cylinder 5 is electrically connected to the controller. During operation, the controller controls the cylinder 5 to push out the arc-shaped positioning plate 6, so that the two arc-shaped positioning plates 6 act on the outer side of the water bucket 3 at the same time to perform centering and positioning on the water bucket 3. In order to prevent the arc-shaped positioning plate 6 from applying too much force to the water bucket 3 when the cylinder 5 pushes out the arc-shaped positioning plate 6 and causing damage to the water bucket 3, in this solution, a telescopic rod is fixedly installed at the output end of the cylinder 5. A first spring 7 is sleeved outside the telescopic rod. The outer end of the telescopic rod is fixedly connected to the arc-shaped positioning plate 6, and the first spring 7 is used to provide a certain buffering force. And a proximity sensor 4 is installed on the top end of the conveyor belt 2 in front of the centering and positioning components. A photoelectric sensor is fixedly installed at the bottom end of the clamping disc 10. The proximity sensor 4 is electrically connected to the driving motor 14 of the conveyor belt 2 through the controller, and the photoelectric sensor is electrically connected to the cylinder 5 through the controller. When the proximity sensor 4 senses that the water bucket 3 passes on the conveyor belt 2, it feeds back an electrical signal to the controller, and the controller controls the driving motor 14 of the conveyor belt 2 to decelerate. When the photoelectric sensor detects the water bucket 3, it feeds back an electrical signal to the controller, and the controller controls the two cylinders 5 to act to push the water bucket 3 for centering and positioning.

[0031] In order to prevent the bottom end of the water filling pipe 8 from damaging the disposable inner liner, a blocking ball 802 is provided at the bottom end of the water filling pipe 8. The blocking ball 802 is threadedly connected to the water filling pipe 8, and a silica gel sleeve can be sleeved outside the blocking ball 802 to further improve the protection effect.

[0032] An air source connection port is provided at the top end of the water filling pipe 8 for connecting an air source. After the water filling pipe 8 drives the disposable inner liner into the water bucket 3, the controller first controls the air source to blow air, so that the whole inner liner expands to fit the inner wall of the water bucket 3, preventing the disposable inner liner from being subjected to excessive water pressure during direct water filling, resulting in too many wrinkles and the phenomenon that the inner liner cannot be fully unfolded.

[0033] During use, first, the open end of the disposable inner liner needs to be passed through the bottom end of the clamping disc 10, and then the open end of the inner liner is manually clamped by a plurality of clamping members 17 in sequence. The non-open end of the inner liner naturally falls, and the lifting guide ring 11 lifts it; after the water bucket 3 is conveyed to the filling station on the conveyor belt 2, the water bucket 3 is centered and positioned by the centering and positioning assembly, and then the controller starts the motor 14 to rotate the wire winding wheel 13 to wind the pulling rope 12. At this time, the water filling pipe 8 can move downward against the elastic force of the return spring 9. The bottom end of the water filling pipe 8 passes through the through hole on the clamping disc 10 and the lifting guide ring 11 in sequence, and pushes the inner liner into the water bucket 3. Since the edge of the inner liner is clamped by the clamping members 17 on the clamping disc 10, and a second spring 18 is arranged between the clamping disc 10 and the pushing guide ring, after the water filling pipe 8 guides the bottom of the inner liner to the bottom end inside the water bucket 3, it can always tighten the inner liner under the action of the second spring 18 (it is necessary to select an inner liner with sufficient length). Before the water filling pipe 8 guides the bottom of the inner liner to the bottom end inside the water bucket 3, due to the pitch of the spring, the clamping disc 10 will move downward by a certain distance accordingly; before filling, the controller first controls the air source to blow air, so that the whole inner liner expands to fit the inner wall of the water bucket 3, and then controls the water supply device to fill water into the inner liner. After filling is completed, the clamping member 17 is loosened, the inner liner is tied and sealed, and then the water bucket 3 is blocked. Finally, the controller controls the motor 14 to rotate in the reverse direction, and the water filling pipe 8 is reset under the action of the return spring 9 to prepare for the next filling operation.

[0034] Embodiment 2

[0035] Compared with Embodiment 1, the difference in this embodiment is that the support frame is a liftable structure, and the lifting function is realized by the controller controlling the hydraulic rod. Setting the support frame as a liftable structure enables the device to adapt to water buckets of different specifications and models for filling.

[0036] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
